R. E. STANTON WEATHER STRIP Sept. 17, 1929.

Filed Dec. '7, 1925 gwuwntot Raymond E. Sranron Patented Sept. 17 1929UNITED STATES RAYMOND E. STANTON, or s'r. PAUL, mmnnsorn' I WEATHERSTRIP Application filed December 7, 1925. Serial No. 73,561.

My invention relates to weather strips and particularly to such stripsadapted to be applied to the edges of movable closures where theclosures are frequently operated.

An object of the invention resides in providing a weather strip whichmay be attached to existing closures without alteration or defacementthereof.

Another object of the invention resides in providing a holder havingfacing grooves in which is positioned a flexible member having themarginal portions thereof lodged in said grooves, said member beingbowed and so held in its application to said holder.

A still further object resides in providing a sealing strip adapted tobe attached to such bowed member and bent over the bowed portion thereofso as to increase its life and prevent the same from receding from thesurface against which the seal is to be effected.

l/Vith the foregoing and other objects in view, which will appear in thefollowing description, the invention resides in the novel combinationandarrangement of parts and in the details of construction hereinafterdescribed and claimed.

' In the drawing illustrating embodiments of my invention:

Fig. 1 is a transverse sectional View of a revolving door illustratingthe application of a form of my invention.

Fig. 2 is an enlarged sectional view of a portion of the structure shownin Fig. 1.

Fig. 3 is a perspective view of the form of weather stripi'illustratedin Fig. 2.

Fig. 4 is a perspective view of a modified form of weather strip similarto that shown in Fig. 3.

In many of the weather strips now in use employing a resilient member,considerable difficulty is encountered in that the resilient member soonfails to seal the opening for which the closure is desired, particularlywhere the opening and closing is frequent. In addition, where a sealingstrip is used the same frequently breaks off or becomes permanently bentadjacent its point of attachment so that no seal is effected therebyrendering the device ineffective for the purpose desired. This isparticularly disadvantageous in connection with revolving doors Wherethe seal is used as a check, sinceas soon as the same 7 fails to engagethe enclosure, the door is permitted freely to spin which frequentlyresults in accidents. My invention overcomes these disadvantages aswillpresently become I apparent. p I I My improved form of weather stripis most advantageously used in connection with revolving doors. Toillustrate the applicatlon thereof I have shown in Fig. 1 anordinarytype of revolving door C consisting of I the usual circularenclosure 27 with a number of wings 28 revoluble about a centralvertical axis 29 situated co-axially with said enclosure. Each of theWings 28 is constructed with stiles and rails 30 which sup port theusualglass panels 31. The upright edges of the wings 28 move in proximity tothe inner surface of the casing 27 and. my improved weather strip isemployed for the purpose of effecting a moving seal between said wingsandcasing. 1 t I The formof weather strip best adapted for use withrevolving doors of the ty e above described illustrated in detail inFig. 3. This weather strip consists of a holder A formed of'a strip ofsheet metal and comprises a back 17 .havingfthe marginal portions 18bent over toward each other and lying parallel with and spaced from theback 17 to provide two faci'n rooves 19 and 20. This holder ispre'feralify of a-width equal to thestile or rail of a door ortwing onwhich the weather strip is mounted'and is permanently secured to theedge thereof by means of screws 37 and 38 shownin dotted lines in Fig.2.f The screws 38 are spaced at suitableintervals and are placed incthecenter of the holder between themarginalpor tions 18 thereof and liesubstantially flush considerably greater than the extreme width of theholder A and of the same length. The marginal portions 35 and 36 of thismember are bent outwardly and inserted into the grooves 19 and 20 withthe sides 33 of the arched portion 32 lying adjacent each other toforman outwardly extending loop, as in-. cated. These two sides arestitched together at 135 to hold the same in proper relation. To preventthe member, from chafing at the extreme edges 4615f the turned marginalportion 18 of member A, said portions are flared outwardly as shown. Theweather strip is attached to theedgesof the stiles-'30 by means or"screws 37 and 38 as previously mentioned ofwhich the screws 38 serve toattach the holder B to the edge-of the wing, w-hilethe'screws 3,7- serveto hold. the resilient member in place so as to permit of; readyremoval. f

Upon the exterior of the side 33. ofresilient member D is stitched at 45a: sealing strip 39 made of felt or other suitable material whichextends outwardly beyond the same as shown in Fig 8. This strip, whenthe door is rotated, is causedto engage the inner surface of enclosure27andis held in contact'therewith. through the resiliency of themember-D. Said strip is made to bend over thecurved or bowed portion 32of member D; so that no sharp'b'reak or fold occurs. In this manner saidstrip is prevented from receding from thesurface of enclosure 27,whereby an effective seal be tween: door and casingis afforded at alltimesyand; the-long life of thestrip insured.

in. the form'of the invention shown in Fig. l, which is quite similarto. that shown inFig. 3, a stifier'resilient memberindieated at Eisprovided. This device consists of a loopedor bowed portion40, themargins 41 and'42 of which lie adjacent one another and are positionedbetween two strips 43. and 44; These; parts are stitched togetherat114e5 to form 'a unitary structure similarto the member D, except thatthe portions 43 and 44 thereof may be made of a substancehavingdifferent resilient characteristics than the bowed portion 40. Thesealingstrip 39 is stitched at 145 to member 40 on one: sidethereof,'the same as in the device illustrated in Fig. '8, itfunctioning in the same manner. In mounting memberE the strips 43' and44: are inserted into the grooves 19 and 20 of: the holder A and held inplace therein by means of screws 37, the same as inthe other formof theinvention. With this type of weather strip, greater pressure of thesealing strip against the inher surface of the enclosure may be had soas to effect a more positive seal.'

The advantages of-my invention are manifest. An extremely-simpleconstruction is provided of which the holder maybe made of? sheetmetaL-bent over as desired, and of which the resilient member may bemade of suitable strips of sheet material which, if desired, may bestitched together, thus pro- Viding a simple and expedient method ofmanufacturing the same. The resilient members may be readily replacedwhen they wear out. The action of the resilient members is such as togive the same a maximum life and at all times to permit the same tofunctionproperly and to eil'ect a positive seal.

Changes in the'specific form of my invention, as herein disclosed, maybe made within the scope of what is claimed without departing from thespirit of my invention.

Having described my invention, what I claim as new and desire to protectby Letters Patent is:

l. A weather strip comprising a holder, a member formed of'resilientmaterial attached to said'holder, and having a. curved portion, asealing strip attached along one edge to said member and normallyextending outwardly therefrom, said sealing strip be ing adapted to bendaround said curved portion.

2. A weather-strip comprising a holder, a member formed of rubberizedsheet material attached to said holder having a curved portion, a feltsealing strip attached to said member and being adapted to bend aroundsaid curved portion.

3. A weather strip comprising a holder having a pair of facing grooves,a resilient member providing a looped portion having portions of itssides in contact and the eX- treme endsthereof diverged and lodged insaid. grooves, and a sealing stria attached to said member along asingle edge thereo1 and extending outwardly from the contacting portionof said member.

In testimony whereof, I have signed my name to this specification.

RAYMOND E. STANTON.
